✨ Enhancing Power Line Safety with Aircraft Warning Spheres ✨

In many transmission line projects—especially where power lines cross rivers, valleys, highways, or wide-open areas—ensuring visibility for pilots is critical. This is where Aircraft Warning Spheres play a vital role.


🔶 What They Do

Aircraft warning spheres provide clear visual marking of overhead conductors, helping aircraft and helicopters identify potential hazards during low-altitude operations. These markers are installed on the shield wires or phase conductors, depending on site conditions.


🔶 Installation Guidelines

To maximize visibility and comply with aviation safety standards:

▪️ Markers must be installed on the highest wire or placed at the same height using other means.

▪️ If multiple wires share the highest point, markers can be alternated between wires to distribute weight and wind load.

▪️ For 30 cm spheres, recommended spacing is 10–15 meters.


🔶 Color & Visibility

An alternating color scheme provides maximum contrast against all backgrounds:

▪️ Use international orange and white marker spheres in alternating order.

▪️ The first and last sphere should always be international orange.

▪️ If fewer than four spheres are installed, all should be international orange.

⚡ These small devices make a big difference in aviation safety and are essential for transmission lines crossing challenging terrain or areas with frequent low-altitude aircraft activity.

Towers aren't the only industry we're involved with. Chimney, transmission line, silo, flare-stack, or water tower structure - we've got the answers to your utility needs. No matter what your marking application might be, we can design a fully ICAO FAA compliant lighting system to meet your facilities requirements.

High-voltage lines are major hazards for low-flying aircraft. Placing beacons on pylons is not sufficient to ensure safety due to the very long spans of cable. - Day Marking The warning ball for high voltage lines is a visual anti-aircraft protection for overhead wires and OPGW wires in high voltage transmission lines. It is recommended that in the case of a sphere with a diameter of 60 cm, the high-voltage line should be marked every 30 meters at the most. - Night Marking Conductor marking lights serve as a specialized category of aircraft warning lights specifically crafted for overhead power lines. In contrast to overhead wire markers that rely on daylight, conductor marking lights are designed to be visible during nighttime. These lights enhance the visibility of transmission line catenary wires in the vicinity of airports, heliports, and locations spanning across rivers. It is built around induction and takes its power from the current of the line, by the intermediary of a multi-winding coil directly installed within the beacon. This allows our system to adapt to every line voltage.
